@jzakiya Don't take me wrong but ... really seems not-so-good-idea, despite being used in Ruby. It was widely discussed by Rust users and they used the same arguments Araq and woggioni (well, sort-of-argument woggioni used ) used here. Some alternatives include pairs of ..< and .. or .. and ..=, both of which have their own problems. A friend of mine always uses a .. b-1 in Nim due to these problems.
Besides, I wouldn't really call criticizing ... "badmouthing Ruby". It's a nice language but it has it's own problems, pretty much like Nim. It's not like you can only praise it infinitely to show your respect to its developers. It's not unfriendly at all, actually, some languages' communities, like Rust's one, criticize their language heavily as well. What's more, it seems really healthy to me. I myself criticize Nim a lot, actually (hi, Araq xD).
